This film by Iranian director Asghar Farhadi (A Separation, About Elly) is well made, though in my opinion he has done better. There are elements in this movie you see in other films of the director: heated marital discussions, secrets and lies coming to the light, cultural differences between the middle class and the working class. However, the end result is not as compelling as in other of his movies.
The action transpires on a single day in Tehran during the celebration of the Iranian new year (a holiday where a lot of fireworks are thrown). The young Rouhi (played by the pretty and talented Taraneeh Alidosti, who was in About Elly), is a working class woman that will soon marry her boyfriend. She gets a temporary job cleaning a apartment in a middle class neighborhood. Upon arriving at the apartment she finds herself in the middle of a heated domestic dispute between Mojdeh and Morteza. Mojdeh (Heyde Tehrani, who's great) suspects that her husband Morteza is cheating on her with the next door neighbor Simin, a woman who set up a beauty salon there after her own marriage broke up. Over the course of the day, Rouhi, the fighting couple, their small son, the wife's sister and husband, and the beautician engage in a series of exchanges and confrontations, as the truth unfolds.
Of course, the central conceit of the film, that the residents of the apartment complex would trust this cleaning lady they barely know so much they would confide to her all their problems, is absurd. At one point, Mojdeh even asks Rouhi to pick her young son at school (she has only known her for a few hours, and already trusts her to fetch her son, whom Rouhi has never met!)
Not knowing much about Iranian culture, I was intrigued by the relationship between Rouhi and her boyfriend. I suppose Iran being a culturally conservative country their relationship before marriage is non sexual, yet they seem so close and loving, especially at the opening scenes of the movie. But the movie doesn't dwell too much in this, a pity since you don't see much about young love in Iranian movies.
